Is exitException intentionally excluded from ExitStatus#equals/hashCode?

[config25]

Body:

Hi,

I noticed that exitException (added in 6.0.3 via GH-4975) is not included in ExitStatus#toString(),
and since equals()/hashCode() delegate to toString(), two instances with different exceptions
are considered equal:

ExitStatus a = new ExitStatus("FAILED", "error", new SQLException("connection lost"));
ExitStatus b = new ExitStatus("FAILED", "error", new TimeoutException("timed out"));
a.equals(b); // true

I'm curious whether this is by design — i.e., exitException is treated as supplementary metadata
and not part of the identity — or if this was simply not updated when the field was introduced.

Either way is fine, just wanted to understand the intent. Thanks!
